Be it known that, l, lvlAusuALL ll. RENO, a citizen ol the United States, residing at Pittsburgh, Allegheny County, Pennsylvania, have invented anew and useful -Improvement in Sound Recordation, of Which the following is a full, clear. and exact description, reference being had to the accompanying drawings, forming part ot' this specification, in which* Figure 1 `is a perspective view, largely diagrammatic, illustrating one embodiment of the present invention; i Figure 2de a topplan view net-tor; A

Figlu'e 3 is a sectional view on the line lll-III of Figure 2;

. Figure avis a view, corresponding to Figure 3, illustrating a slightly modified form of the present invention, and

Figure '5 is an enlarged detail view.

The present invention relates ybroadly to sound recordation, and' more particularly to improved method andapparatus for increasing the eiic-iency ot' commercial recording machines.

l. am aware that it has heretofore been proposed to couple either the transmitter or the receiver of a telephone, or similar appa'- ratus, to the tube ot' `a\comn'1erci.al recording machine, commonly referred to asa dicta- Iphone, and thereby make it possible to pro- `,cure permanent.records ot' telephonie and There have been several objections to devices of this vgeneral nature, these objections being due, among other things, to the fact that ordinary telephone. receive-rs and transmitters are not very sensitive and there is no effective method of damping the vibrations of the vibrating element. Also, the. means of conneotingthe sound producing device to the recording machine has not proven very etli-v cient.

The present invention .embodies several important features overcoming the recordaof the contion of rasping, raucous sounds, such as pro-l duced by loud voices or certain notes capable of setting up interfering vibrations,

either sympathetic or otherwise, and pro-- vides a more sensitive apparatus whereby recordation. of either telephonie' messages,

-from tlie acousticon.

drawing, there is diagianunatically illustrated an electrically operated sound concentrating and amplifying device 1. This device is preferably of the nature ordinarily used by deaf people and referred toas an .'acousticon, this type of instrument having been found highly efficient due to its sensi'- tiveness and accuratesound Wave transmission. desired manner, as by a 'cable or cables 2 with either one or a plurality of receivers These receivers are preferably of the type usually supplied for usea's ear pieces 1n, connection with the acousticon. The lie-- ceivers in turn are adaptedto mechanically transmit, by means of diaphragms 4, the vibrations electrically transmitted thereto These vibrations are transmitted "through a suitable tubular conducting.,r member .to the recording diaphragm containing box B of a commercial recording machine such as the dictaphone.

The present invention lprovides an etiicient i 1,560,7aaj

.The acousticon is connected in any i meansfor connecting the receiver with the p dictaphone. This eonectionmay comprise a suitably shaped casing 5 of any desired inaterial having an enlargedcilp-shaped 'upperend 6 adapted to rec'eive'the receiver-.3.

The receiver may be held in' placel by a suit- 4 able closure 7. Communicating with' the,

chamber-6 is a tubular passage 8 which pas' sage isot' such diameter that imay be easlly v.

slipped directly on tot-he ltub ar sleeve provided on the box B of the dictaphone.` I

have found that unless some sound modifying or modulating means is provided, sound willbe recorded in such manner .aslto make its subsequent transcription difficult or unpleasant. In order to prevent the transmission of harsh sounds` I provide a sound modifying and modulating 'means within the casing 5. In the form ot the invention illustrated,- this means comprises a Series of independent diaphragme 9 supported lv.for

free vibration on the shoulders 10 and m62 clamped in position between the receiver and the shoulder. The passage Sxis preferably closed at its upper end by'a suitably shaped grid 11'-, which prevents undue-distortion `of the `diaphragme 9, which dia-4 phraglns are preferably of material having sound modifyihgo vmodulating character be provided?".withflopenngs 112.*permittingi l' ril-idd electrical connection to easily bo made, by the use of detachable plugs, with therecoiffer.

i have found that with au apparatus of this` character it is possible to place the acousticon at auf,Y desired point in a room and accurately record conversation, dictation or thc like without speaking directly into the acoustiron.

,in Figure l. there is illustrated a slightly modified lorm ot' apparatus in which parts corresponding to thc parts already described are indicated bythe same reference characters having a prime aliixed theretoI ln this construction the acousticon l is held in position within a supplemental casing 13, suitably attached to the casing 5 in any desired manner. lt desired, spring clips lniay be provided for holding the acousticon-in position. Preferably, with an apparatus of this character, there will be provided suitable cushioning material, such as felt lli between the acousticon and the closure 7. it

'wili be apparent that battery connection may be -inade with the acousticon l in any desired n'ianner, or the aconsticon may be huilt with a seit-contained battery.

.in certain cases it is desirable to record speeches and transcribe the same almost immediately. liVhere this is the case, the acousticon may be connected to a plurality of receivers 3, each oi which cooperates with a dierent dictaphone. ln this manner, it will be possible' to use first one or" the dictaphones and record a certain amount of the speech thereon, anch'just, before stopping the iirst dictaphone, pnt. a second dictaphone in operation, and soon, using one dictaphone after the other in succession, Vith a short period'ot overlap in the operation ot a preceding dictaphone with that'otl a succeeding one so as to insure recording of the entire speech, new records being substituted for the used records as cach dictaphone is taken out ot' operation. Ylhis permits transcription ot the record troni the dictaphone substantialiy simultaneously with its' recordation.

ln other instances, it may be desirable to retain the usual tube l5 which is provided for use with dictaphones. ,ln order to permitthis operation, the casings may be Ylormedv with a peripheral bead i6 adapted to coop-A erate with the spring lingers 1T usually provided to receive the glass mouth piece of the dictaphone.

The advantages ot' the present invention arise from the method hercinllisclosed jfacilitating.r the rccordation of'sound, improving the etticiency of the recording apparatus, and obviatng the recordation of undesirable sounds. y

A further advantage ot' the` present invention, inherent in thc use ot the acousticon, arises from the fact that an acousticon of standard construction may. if desired, be carried about leither in the hand or attached to the clothes of the person dictating,whereby freedom 'of movement ispermitted and accurate' recordati-on insured.
